LMM: Bad Hesitation

[Dave Burley]

Hi everyone, I am running a 2oo7 Duramax LMM with a Banks system and have put duel exhaust and fresh air intake on thats it for now, what I am experiencing is when I put the throttle down some times, worse when hot there is a huge lag before I have acceleration and black smoke, can anyone help me with this?

Sounds like your talking about turbo lag a little bit...can you adjust the low boost fueling on your programmer?

Your truck is always going to have just a little dead spot when you first stomp on it but it shouldn't be horrible by no means.

Ok thanks, I will try that.
